Why we like it

Mesh Combine earns its place in the Superhive library by folding mesh merging, UV remapping, and PBR atlas generation into a single Combine action.

What is Mesh Combine?

Mesh Combine is a Blender add-on for optimization work: it merges multiple selected objects into one mesh and packs their textures into an organized texture atlas. It is aimed at preparing assets for Unity, Unreal Engine, or web-based 3D viewers, and uses optimized pixel-buffer processing to generate atlases in seconds.

The add-on covers a full PBR workflow, generating synchronized atlases for Color (Albedo), Normal, Roughness, and Metallic maps simultaneously. An intelligent shelf-packing algorithm arranges textures to maximize space and prefers square atlas dimensions up to 8K. UV remapping is automatic: the tool duplicates your objects, adjusts UV coordinates to fit the new atlas, and joins them into a single clean mesh.

The workflow is non-destructive, so original objects remain untouched while a new optimized version is created. In use, you select the meshes to combine, choose which texture maps to include in the Sidebar panel, and click Combine. The add-on creates a new object with a custom "Combined Atlas Material", and the generated atlas can be saved from the Shading panel.

Who is Mesh Combine best for?

Mesh Combine is best for blender users preparing optimized assets for Unity, Unreal Engine, or web-based 3D viewers who need combined meshes and PBR texture atlases.

How much does Mesh Combine cost?

Mesh Combine is completely free to download and use.

Frequently asked questions

What Blender versions does Mesh Combine support?

Mesh Combine lists support for Blender versions 3.6 through 5.0, covering a wide span of releases. It also works with the Cycles and Eevee render engines. If you run a version within that range, the add-on is designed to fit your setup. For versions outside the listed range or to confirm behaviour with your exact build, check the developer's page for the most current compatibility details before installing.

Does Mesh Combine change my original objects?

Mesh Combine uses a non-destructive workflow, so your original objects remain untouched. When you run the tool, it duplicates your objects, adjusts their UV coordinates to fit the new atlas, and joins them into a single clean mesh, creating a new optimized version of your selection rather than altering the source. This lets you keep your originals intact while producing the combined result as a separate object with its own material.

Which PBR maps can Mesh Combine pack into an atlas?

Mesh Combine offers full PBR support, generating synchronized atlases for Color (Albedo), Normal, Roughness, and Metallic maps simultaneously. You choose which of these maps to include in the Sidebar panel before combining. The intelligent shelf-packing algorithm arranges the textures to maximize space and prefers square atlas dimensions up to 8K, and the resulting atlas can be saved from the Shading panel after the meshes are combined.

How do I use Mesh Combine in Blender?

Mesh Combine follows a short workflow: first select the meshes you want to combine, then choose which texture maps to include, such as Color and Normal, in the Sidebar panel. Clicking Combine creates a new object with a custom "Combined Atlas Material". From there, you can save the generated texture atlas in the Shading panel. The add-on handles the UV remapping and mesh joining automatically as part of this process.

Is Mesh Combine free?

Mesh Combine is listed as free in this catalog, so no price appears on this page. The add-on is distributed under a GPL license. Because licensing terms and any purchase options can change over time, check the developer's page for the current details before you rely on a specific arrangement. There you can also find the documentation and a demo video that accompany the add-on for a closer look at how it works.
